LOCK.

' Specification of Letters Patent.

Patented Apr. 20, 1915.

Application filed. December 26, 1914. Serial No. 879,084.

To all whom it may concern Be it knownthat I, CHAnLEs G. TAYLOR, acitizen of the United States, residing at Los Angeles, in the county ofLos Angeles and State of California, have invented certain new anduseful Improvements in Locks, of which the following is a specification.

This invention relates to improvements in looks, and it is an object ofthe invention to provide a simple inexpensive lock which is providedwith an interior locking means adapted to be shifted by certainmovements for locking and unlocking the shackle portions of the look.

It is also an object of the invention to pro vide a lock withcooperating shackle portions and an interior shifting tumbler adapted tobe moved in accordance with the position of the lock for controlling the'action of said shackle portions. 7

It is a further object of the invention to provide a lock with shacklecontrolling members in which a gravity actuated member within the lockstructure is employed to lock and unlock the shackle portion of thedevice.

With these and other objects in view the invention comprises certainnovel constructions, combinations and arrangements of parts as will behereinafter fully described and claimed.

In the accompanying drawing: Figure 1 is a side elevation of alockconstructed in the shackle portions in locked position' Fig. 5 is a sideelevation of one of the shackle members with its controlling mem-' beror disk. Fig. 6 is a similar view of the other shackle member.

It is a purpose of the present invention to provide a lock, usually ofthe padlock type which is a keyless lock and has separable shackleportions adapted to be brought together to form a complete shackle, themembers or disks which carry the shackle member being controlled by atumbler or disk which may be shifted for looking or unlocking the saidshackle portions without the use of a key.

The details and features of the invention will now be more specificallydescribed with reference to the accompanying drawing in which- 1 and 2indicate cooperating shackle members, 3 and 4 disks carrying the sameand 5 a tumbler or shifting member 'for locking the shackle members.

The members 3 and 4 are preferably flat disks or circular membersadapted to be applied upon each other, though of course they may be madein other shapes if desired without departing from the spirit of theinvention. The members 3 and 4 are pivotally connected at the center bya rivet or pivot bolt 6, so that they may turn upon each other. Theshackle portions 1 and 2 usually project from the edges of the saidmembers 3 and 4 and are generally offset at 7 and 8 so that the greaterportion of the said shacklemembers will lie in the same plane as will beclearly understood by reference to Fig. 3.

The ends of the shackle members 1 and 2 are preferably made withportions which lap upon and pass each other sufiiciently to forma strongcompleted shackle when the said members are brought together. The saidends are usually bifurcated at 9 and 10 and one portion turned in onedirection and the other portion in the other direction to form a firmjoint between the shackle members. The portion '11 is bent parallel withthe portion 12 upon the opposite shackle member so that they may lap inparallel position upon each other as shown in Fig. 3.

The other portions 13 and 14 of the bifur cated shackle ends lap uponeach other in the other direction and thus extend diagonally across theportions 11 and 12 as shown in said Fig. 3. The shackle portions cannotbe sprung in either direction with respect to each other when formed inthis way and afford a strongand complete shackle for the lock when inclosed position.

In order to lock the shackle members the disks. or members 3 and 4 areprovided with openings or slots 15 and 16 which preferably extendradially with respect to the pivot 6 and which coincide or fit one overthe other when the shackle members are closed, so that a tumbler memberor disk 5, which is made of thicker material than the members 3 and l,may extend into both of the openings 15 and 16 and when occupying thelower portions thereof as shown in F gs.- 1 and t, will lock the saidmembers place.

3 and 4 against movement upon the pivot pin 6. In order to be able tomove the members 3 and 4 when it is desired to open the shackle members1 and 2, the openings or recesses 15 and 16 are provided with offsetextensions 17 and 18 at their inner ends, but extending in oppositedirections with respect to each other. It will thus be evident that whenthe tumbler 5 is brought to the inner ends of the openings or recesses15 and 16, the members?) and 4 may be turned upon their pivot to theextent permitted by the length of the offset recesses 17 and 18.

In using the look when the shackle members 1 and. 2 are brought togetherand the said lock is held so that the tumbler 5 will drop into the lowerportion of the recess formed by the superposed openings 15 and 16, themembers 3 and 4 will be locked and the shackle members 1 and 2 will befirmly held in their closed positions. When it is desired to open them,the lock must be turned into a'suiiiciently inverted position to permitthe tumbler 5 to roll or drop to the inner ends of the openings 15 and16, when as indicated in Fig. 2, the membersB and 4 may be moved on thepivot 6 as the tumbler 5 will engage the offset recesses 17 and 18-. Theshackle members 1 and 2 may of course be pushed together when it isdedrop again so as to lock the said shackle members. The openings orrecesses in the members 3 and 4 must of course be closed to properlyhold the tumbler 5, movably in The said recesses need not of courseextend entirely through the material ofthe members 3 and 4 as will beevident, but side or check plates" 19 and 20 are preferably used andapplied upon the outer faces of the members 3 and 4 to provide walls forinclosing the said recesses 15 and 16 and their offset extensions 17 and18. The said side enough to be used in the place of any ordi narypadlock. It is quickly and easily locked and unlocked and requires nokey or member separate therefrom for accomplishing the locking andunlocking operation. The device may-also be employed as a nov- Copies ofthis patent may be obtained for The said plates may be shackle members.

elty or puzzle, there being nothing upon the exterior of the lock toindicate in any way, how the shackle-members are to be released andpermitted to open. Thus only "those who learn the secret of the lock'canoperate it and unlock the shackle. V

' What is claimed is: 1. A look having separable shackle mem bers and agravity actuated tumbler adapted to be shifted by altering; the positionof r dence, a tumbler disk movable in said recesses for locking thedisks. against movement, the said recesses having offset extensions forreceiving the tumbler when the partsare in unlocked position, andshackle members carried by'said disks.

3. A look comprising .shackle carrying members mounted to revolve withrespect to each other and having shackle armsprojecting therefrom, thesaid arms having interlocking edge portions adapted to form a firm jointbetween the parts, the said mem-l bers having angular recesses adaptedto be brought into coincidence and a disk of sufficient thickness toextend into both recesses for lockingthe shackle arms.

4. A look having a separableshackle, pivoted disks carryingthe membersof said shackle and having superposed recesses "formed therein, saidrecesses havinglateral extensions pro ect1ng 1n opposlte directions withrespect to each other from the inner erdsof said recesses, andg'ai loosetumbler end of the said recesses the shackle memberswill be locked, andwhen the lockiis inverted and the tumbler permitted to fall into theother ends of the recesses, the

shackles will be permitted to open.

5. A look having disks pivoted with re spect to each other and shacklemembers projecting therefrom,the ends of said members having splitportions bent in opposite directionsfor forminga firm joint at the endsof the'said shackle members and means for preventing the'movement of thesaid disks on their pivot points to prevent the unauthorized opening ofthe 7 said .100 engaging said recesses, the structure being such thatwhen the tumbler 1s at 'the outer;
